My mother was sweet and fun-loving throughout her life, but is now angry and violent, becoming more so as her dementia worsens. When family members are present and she is engaged in an activity, she is nice, like she always was. but as soon as we leave, she becomes depressed and angry, pulling my father out of his wheelchair, attacking nursing staff, and yelling angrily. Many medications and dosages have been tried without success. The nursing staff is on a 3:1 ratio to patients, yet, there is simply not enough family and staff to be with her all day. All children live out of state.
